WebRab7 with Vps39 and Vps41 subunits of the mammalian HOPS complex (Rink et al., 2005; Poteryaev et al., 2010; Sun et al., 2010). However, thus far, direct binding to Rab7, and whether any mammalian HOPS subunit acts as a Rab7 effector, has not been demonstrated. Recently, it was also reported that the Rab7 Web22 dec. 2014 · Intriguingly, Rab5 and Rab7 both bind to the hexameric tethering complex HOPS (“homotypic fusion and protein sorting”). Rab5 binds to subunit Vps11 (Rink et al., 2005). Rab7 interacts with subunits Vps39 and Vps41, but SAND1/Mon1 also interacts with Vps39, which in yeast is a Rab7 GEF (Peralta et al., 2010; Plemel et al., 2011).
